Government indicates that it aims to have the regulations in place ahead of the May general election for minimum energy efficiency standards (MEES)

The non-domestic minimum energy efficiency regulations for England and Wales will mean that by 01 April 2018, all relevant properties will have to be improved to a minimum energy efficiency standard before being let to tenants, except where certain exemptions apply. This means that landlords can no longer pay lip service to energy efficiency. Whereas it was once a worthy aspiration, it is becoming as fundamental as fire safety or building regulations.
